Pipe Bedding 4/20 mm delivered in Basingstoke
4/20 mm graded bedding is the workhorse size for larger-diameter and deeper drainage. The wider grading gives strong interlock and good haunch support under 225 mm and above, and it places quickly in volume — which matters when a trench run is measured in hundreds of metres rather than tens.
Into Basingstoke and across Hampshire we supply it loose by tipper, by grab lorry where a stockpile has to be loaded or reached over a boundary, or in bulk bags for plots a lorry can't discharge into. 24–72 hours on stocked lines across RG21–RG29 postcodes. Artic loads for business-park earthworks, 8-wheel tippers for estate roads, grab and bulk bags for tight plots and landscaping.

- Deep trench work where haunch support is critical
- High-volume adopted sewer and highway drainage runs
- Attenuation and soakaway fill where void ratio matters
Chalk subgrade is the local factor — arisings often behave differently to the clay further east, and capping choice matters on wet-weather working platforms. Business-park and distribution work runs on artic loads to programme; housing sites take phased plot-level bedding, sand and topsoil.
What shapes Pipe Bedding 4/20 mm supply in Basingstoke
Drainage packages on business-park, distribution and housing groundworks around Basingstoke take Pipe Bedding 4/20 mm in daily call-offs rather than one bulk drop, so bedding lands as each run is dug rather than sitting in the way. Business-park and distribution sites on programme, plus phased housing plots decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing chalk and clay arisings where wet-weather handling changes the plan, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Andover, Alton and Newbury.
Questions we get asked
Is 4/20 mm suitable for adopted sewers?
It is widely used for adopted drainage bedding and surround, but the size and class must match the adopting authority's detail and your engineer's specification. We can supply grading and test data to support submission.
Can you deliver 4/20 mm in artic loads?
Yes — for bulk civils programmes we deliver 28–29 tonne artic loads direct to site on a booked call-off schedule, which is the lowest cost per tonne where access allows.
Which north Hampshire areas do you cover?
Basingstoke, Andover, Alton, Fleet, Tadley and Whitchurch, plus Newbury and Winchester on the same routes.
Material out as well as in, around Basingstoke
Most deliveries into Basingstoke pair with a removal: the lorry takes your arisings to a licensed facility and comes back loaded, so you pay for one movement rather than two.
